DIP Switch Settings
Use the DIP switch to activate the following operations.
Default setting for DIP Switches is “OFF (Disable)”
position.
DIP 1: LLB – Local Loopback Enable or Disable at copper
port. The Local Loopback function is used to check if the
copper segment is functioning properly. The default
setting for LLB is Disable. Turn the switch setting Enable
to perform the Local Loopback function test.
Fig: Local Loopback (LLB)
Note: Enabling the LLB function means, the converter’s
normal function will be stopped.
DIP 2: RLB – Remote Loopback Enable or Disable at
fiber port. The Remote Loopback function is used to
11
1000Base-T to 1000Base-SX/LX Converter
check if the fiber segment is functioning properly at remote
site. The default setting for RLB is Disable. Turn the

16
1000Base-T to 1000Base-SX/LX Converter
Connecting Fiber Cable
When connecting fiber cable to a 1000BASE-FX port on
the Converter, be sure the correct type – SC or WDM connector is used. Follow the steps below to properly
connect fiber cabling:
1. Remove and keep the fiber port's rubber cover. When
not connected to a fiber cable, the rubber cover
should be replaced to protect the fiber optics.
2. Check that the fiber terminators are clean. You can
clean the cable plugs by wiping them gently with a
clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber optic cables
will impair the quality of the light transmitted through
the cable and lead to degraded performance on the
port.
3. Connect one end of the cable to the SC/WDM port on
the Converter and the other end to the SC/WDM port
on the other device.
4. Check the corresponding port LED on the Converter
to ensure that the connection is valid. (Refer to the
LED chart in next section)
Note:
When inserting the cable, be sure the tab on the plug
clicks into position to ensure that it is properly seated.
17
1000Base-T to 1000Base-SX/LX Converter
Warning Because invisible laser radiation may be emitted
from the aperture of the fiber port when no cable is connected,
avoid exposure to laser radiation and do not stare into the
open apertures.
18
1000Base-T to 1000Base-SX/LX Converter
